SPECIFICATION forming part of Letters Patent no. 294,875, dated March 11, 1884.

Application filed January 3, 1884. (No model.)

To all whom it may concern:

Be it known that we, REMI HENRY and HIRAM B. TAYLOR, of New Rochelle, in the county of Westchester and State of New York, have invented a new and useful Improvement in Upright Tubular Boilers, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional rear elevation of our improved boiler. Fig. 2 is a sectional plan view of the same, taken through the line 00 x, A

Fig. 1. Fig. 3 is a sectional plan view of the same, taken through the broken line y y, Fig. 1. Fig. 4. is a side elevation of a connectingtube.

The object of this invention is to facilitate the generating of steam and economize fuel in using steam boilers. i

The invention consists. in an upright tubular boiler constructed with an annular basetube connected with the lower ends ofa circle of upright tubes, which are connected with a circle of shorter intermediate tubes and a central annular tube by connecting-tubes having right and left screw-threads upon their ends. The circular base-tube is provided with a blowoff cock and an inlet water-pipe, and the central annular tube is provided with a steampipe, as will be hereinafter fully described.

A represents the base or foundation, and B the casingor shell, of our improved boiler.

Upon the base A rests an annular tube, 0, which may be rectangular or circular in crosssection, and which is provided with a blowoff cock, D, and a feed-pipe, E, as shown in Fig. 1.

Into the annular tube 0 are screwed the lower ends of a number of upright tubes, F.

Within the circle of the upper parts of the tubes F is arranged a circle of shorter upright tubes, G, which can be made larger than the tubes 1?, or of the same size, as may be desired.

At the center of the upper part of the boiler is placed a large tube, H, having a flue, I, through its center. The annular central tube, H, and the intermediate tubes, G, are closed at both ends, and the outer tubes, F, are closed at the upper end. Each intermediate tube, G, is connected at its upper and lower ends with the annular tube H and with the tube F upon the same radial line with it by connecting-tubes J, which have a right screwthread upon one end and a'left screw-thread upon the other end, so that the said connecting-tubes can be readily inserted and removed.

The upper ends of the other tubes F are con-- nected by tubes J, having right and left screw threads upon their ends, with the annular tube H. The upper parts of the tubes F G H and the upper connecting-tubes, J, from the steam-chamber and the steam-pipeK are connected with the upper end of the annular tube H. With this construction the water can pass freely from the annular tube 0 through the tubes F to the tubes G H, and will stand at the same level in all the tubes F G H. The space beneath the tubes G H forms the firechamber, and access is had to the said chamclaim as new and desire to secure'by Letters Patent 1. An upright tubular boiler constructed substantially as herein shown and described, and consisting of the annular tube C, the long upright tubes F, the shorter intermediate tubes, G, and central tube, H, having center flue, I, and the connecting-tubes J J, having right and left screw-threads on their ends, as set forth. a 2.
